Vehicles fire suppression system

The detexline automatic fire suppression system was developed due to the requirement from mining companies for a system that was reliable and eliminated trouble spots.
By eliminating electricity and pressure (from the tank and detection lines) and increasing simplicity, we found a solution that met the requirements for a rough fire suppression system for vehicles: the detexline.
Whether for vehicles, heavy equipment or industry, our fire suppression systems are highly reliable.
With precise detection and a liquid extinguishing agent, a fire is quickly detected and suppressed by the cooling power. There are no false discharges, leaks and electrical or battery problems.

Vehicles equipped with automatic fire suppression systems bring several advantages: safety for the driver and passengers, avoid loss of equipment and unnecessary stops.

Functions and mode of operation of a Fire Suppression System for vehicles

What are the features of the fire-suppression system?

The fire-suppression system is based on the principle of a fine spray extinguishing system. The protecfire nozzles spray the extinguishing agent TiboRex Absolute as very fine droplets. The extinguishing agent droplets wet, impregnated and cool the burning surfaces.
Through reflections and turbulence, the extinguishing agent also reaches adjacent areas, which enables the entire engine compartment to be protected.

Other features:

  • Unpressurised standby mode for improved safety: The fire-suppression system is not pressurized until it is triggered.
  • Low maintenance: first regular component replacement after 5 to 10 years.
  • Self-sustaining without external energy: protecfire suppression systems operate pneumatically-mechanically. This means that they do not require any additional power supply.
  • Automatic and/or manual triggering: Automatic triggering is effected by fire detection elements. The fire-suppression system can also be triggered by a pneumatic manual release mechanism.

How does fire detection work?

protecfire uses thermopneumatic fire detection elements to detect fire. These elements only trigger the fire-suppression system if a specified temperature is exceeded. Failure due to the failure of electrical components is thus ruled out.
Fire detection elements with different triggering temperatures can be used because the engine compartment is not a thermally homogeneous area, but contains different temperature zones.

What happens in the event of a fire?

The fire detection elements are connected to a combined control and extinguishing line, the detexline. When a fire detection element is heated to its trigger temperature, a mechanism opens the built-in argon propellant cartridge. This causes an increase in pressure in the line. The pressure increase opens an N2 propellant cartridge in the extinguishing agent container. The released propellant presses the extinguishing agent through the line to the extinguishing nozzles.

Latest certification process 

protecfire conducted at RISE (Sweden) tests for fire suppression systems intended for engine compartments according to SP Method 4912, UNECE R107, AIS 135 – SPCR 183 or SPCR 199 (P-mark).

Tests made with 4 liters detexline container, with Tiborex Absolute extinguishing agent.
All fire scenario tests were successful.

Fire suppression systems certifications

Vds Approved

VdS tests security products and assigns them to classes which are used by insurance companies and the police.

With its strict certification regulations, VdS provides for high-quality products that guarantee the best results and security even when used under the most adverse conditions.

R-107 Certified

This document includes a fire-testing procedure for fire suppression systems for engine compartments of buses and coaches and includes four tests extracted from SP Method 4912 (SP is a Technical Service for UNECE Regulation No. 107)

The requirements of fire suppression systems apply to: single-deck double-deck rigid or articulated vehicles Category M2 or M3 and specifically vehicles having a capacity exceeding 22 passengers in addition to the driver – “Class III”. Class III vehicles are constructed exclusively for the carriage of seated passengers, more commonly referred to as “coaches”.

CESMEC Certified

Certification intended for Mining vehicles and equipment

National Standard Institute from Chile (INN), published “Certificación de Conformidad – Modelos de Certificación ISO/CASCO, INN 100-611” Which is a translation of the original text in English “Technical Assessment and verification of conformity to standards and specifications”

Purpose from the certification:

This method assesses the fire suppression performance of fire suppression systems under mock-up operational conditions. For this purpose, several different types of fires are ignited and stabilised inside an enclosure with engine compartment characteristics. Fire suppression systems are then evaluated based on its ability to extinguish the various test fires.

SP Method 4912 tests fire suppression systems intended for engine compartments in a well-defined and objective way. Systems are subjected to realistic fire scenarios that can occur on and around a vehicle or machine, as a means to evaluate their performance. The system tests are based on the geometry, obstructions and air flow typically found in engine compartments. This allows for rapid performance evaluation under reproducible and repeatable conditions.

Fire Suppression system testing Method:

The fire suppression system may be subjected to the test scenarios listed below. In the end, a system will achieve a ranking based on the number of tests completed and the conditions, e.g. ventilation rates and/or level of openness of the testing rig, under which this was achieved.

High Fire Loads

Evaluate the fire suppression system’s ability to suppress large fires. As an example, these large fires may originate from a broken pressurised fuel hose that sprays against hot surfaces, resulting in rapid fire development. It is crucial that fire suppression systems can effectively deal with these fires, as they may even occur if reliable detectors are installed.
Low Fire Loads

Are used to judge the system’s ability to deal with small fires in an enclosure. These small fires can be difficult to extinguish and require that the distribution of suppressant in the compartment is effective.

Systems that can extinguish our Class A Fires have proven their ability to deal with deap-seated fires in fibrous materials. Examples of such materials are sound insulation, rubber and/or some plastics, which commonly act as a secondary fuel source.
Obstructions are often present in engine compartments. This is emphasised in our Hidden Fires test. 
Here the suppression system shall extinguish a small obstructed fire that is out of reach for direct fire suppression. As such, the total flooding capabilities of a system is evaluated.

Certain components in engine compartments may still be hot enough to ignite flammable material after a fire has been extinguished. Our Hot Surface Re-Ignition test evaluates the fire suppression system’s performance in cooling down those hot surfaces.
